My tastes are also not sophisticated. Basically, I drink whatever's in the coffee mess -- both in the military and civilian work as a software engineer there would always be a big pot of coffee.
My friend was the opposite and was very particular about her coffee (had to be a particular blend from Starbucks) ... also about her bottled water, so when she was in the hospital I would bring her her preferred water. In Europe she didn't care for the coffee, not even in Italy, so as a treat in Strasbourg I took her to a Starbucks I had spotted in my Maps app.
My last job was from 1995 to my retirement in 2018. My job interview was at 8AM. Before going in, my boss-to-be took us to the break room for coffee. Since we just emptied that coffee urn, I immediately made a fresh pot for the next person, pausing only to ask how many scoops. Before noon, they called me with a job offer. My version of the events was that the deciding factor must have been that I was willing to make coffee instead of leaving a thin layer of coffee in the urn (maybe about 10 ml) as far too many co-workers tend to do.
I'll have a cup of coffee in the morning because I like it, but I'm not dependent on the mythical "first cup". I use Trader Joe's French Roast in a Bialetti Moka Express. I add sugar and creamer in my coffee, though never in tea. I also keep some International instant coffee on hand for when I just want a quick cup. My friend had given me a simple drip setup, but I've only tried to use it once but couldn't figure out how to measure how much water I'm adding as I pour it from my tea kettle so I gave up on it.
My father always took his coffee black. In the Navy (he was a Seabee, a "dirt sailor") you could always find coffee, but rarely anything to put in it. He could only have his coffee black, so he learned to like it that way. In a similar vein, right before I enlisted an Air Force vet who had been stationed at Thule, Greenland, told how he would provision his parka (they have big pockets) with survival packets of sugar, creamer, instant coffee, hot cocoa mix, instant soup mixes, etc, since he could always find hot water and maybe coffee, but usually nothing else.
